The present invention relates to the production of cigarette-mouthpieces and their insertion into the corresponding cigarette tubes or shells, and is intended to solve the difficulty of producing these mouthpieces from one endless paper band. Apart from the fact that the ready-rolled mouthpiece is severed from the band while the next one is cut with an oblique end the task requires an essentially different treatment of the paper when being rolled to form the mouthpiece as compared with the method of producing cigarette-mouthpieces in which a series of pieces of paper to be rolled into mouthpieces are introduced ready cut and separately. It will therefore be seen that essential differences arise between the present invention and that described in German patent to Harnisch, No. 88,113, November 24, 1895. Whereas in the latter apparatus the point of the paper strip is held loosely by friction in the slit of the winding-spindle 3 and is loosely rolled Within the larger tube 5, according to the present invention, while the strip still form-' ing part of the supply-band is firmly taken hold of by a rolling-up device, acting like curling-tongs, and rolled, the inertia of the supply-roll of paper, aided or regulated by a brake device, assisting in causing the paper to be rolled up firmly. By this means not only is it made possible to employ a continuous-supply band of paper, but the natural stiffness of the paperis thereby broken or reduced, although not to suchan extent as to deprive it of all elasticity, it being still able tounroll to a slight extent when left free inside the cigarette-shell, though not so decidedly as is the case with mouthpieces $eria] No. 709,786. (No model.)

produced in the manner described in said patent. Such decided unrolling within the shell has the effect of pressing the windings close to the shell, leaving a comparatively large central space occupied only by the small S'shaped end of the paper, which will imperfectly retain short or small tobacco Within the cigarette, Whereas the elasticity of the spiral formed according to this invention is sufficiently reduced to cause the spiral to loosely but effectively fill the end of the tube or shell which it is destined to occupy. The firm rolling up of the paper is, moreover, increased by the arrangement of a presser acting radially on the rolling-up device and the paper spiral forming upon it.

The additional advantage arising from the avoidance of the difficulty of having to feed regularly and singly thin sheets of paper from the supply-stacks needs no furthercomment.

It is only necessary to mention, as an example, the automatic post or business card machines, which all suffer from the drawback referred to, which has not been remedied in spite of repeated efforts, and compared with post or business cards the handling of these thin papers is very much more difficult.

In the accompanying drawings, Figure 1 is' an elevation of the apparatus,partly in longitudinal section, on the line I I of Fig. 2, the paper feeding and cutting devices opposite the rolling-up device being,however, omitted. Fig. 2 is a plan viewshowing also the feeding and cutting devices. Fig. 3 is a vertical section through th e feeding, cutting, and rolling-up devices on the line III III, Fig. 2. Fig. 4, is a transverse section on the line IV IV, Fig. 1, Figs. 5, 6, 7, 8, 9,10, 11, 12, and 13 being detail views, hereinafter referred to.

The paper band 1), Fig. 3, the breadth of which is equal to the length of the mouthpieces to be formed, passes from a bobbin or holder over the feeding device a,guide-plate h, under the knives c and d, and enters with its point (see Fig. 6) between the open jaws of the rolling-up device c, which is at that time in the position as shown inFig. 1,.

The rolling-up tongs are fixed with their shank in a tube 1, which is revoluble in the bearings, but cannot be longitudinally dis 2 placed, said-tube being rotated by means of liquely at the same time.

Wheel-gearing, Figs. 1 and 13, as long as the semicircular or segmental toothed Wheel 2, fixed on and driven by the shaft 3, is in gear with its corresponding transmitting-wheel. When the tube is at rest, the jaws of the rolling-up tongs are open, the jaw 5, pivoted ate, Figs-1 and 5, being pressed down by a spring. As soon as the pointed edge of the paper comes into position between the jaws of the rollingup tongs the cam-disk 6, by means of the lever 7and ball-joint connection 8, presses forward the plunger-shaft 9, which is revoluble with the hollow spindle 1, and thereby moves forward the thin rod 10 and its end ring 11, in doing which the lever 7 passes from position I into the position II, Fig. 1. In consequence of this change of position the ring 11 is pushed over the shoulder 12 of the jaw 5, thereby closing the jaws over the paper strip 19 and firmly holding it. At the same time the rolling-up tongs are set rotating,-thus winding around them firmly and tightly a certain length of the paper strip, a presser 13, Figs. 7 and 8, actuated by a spring, Fig. 1, also contributing to cause the paper convolute to be wound up tightly. This part of the operation being finished, the break in the series of teeth 14, Fig. 13, allows the rolling-up tongs to rest for a short time. During this time the already partly-formed convolute is cut off from the paper band, the new end of which is cutoff ob- The first operation is effected by the knife (1, Figs. 2, 3, and 11, cooperating with an under knife, Fig. 3, and the second by a knife 0, the edge of the plate 15 serving as the under knife. The knife (1 is attached as a leverarm to a shaft 16, Figs. 2 and 11, which is intermittently operated by means of connecting-rods and a cam-disk, as represented in Fig. 11. A plate 17, Figs. 2 and 3, is fixed to the top of the knife (I and extends over and rests upon the top of the knife 0, so that the downward movement of the knife at will be communicated to the knife 0, which is pivoted upon a fixed point 18, Fig. 10. A spring 19, attached to the knife 0, (see Fig. 10,) tends to return the knife 0 to normal elevated position, and in its upward movement will elevate the knife d by coming in contact with plate 17, as will be readily understood. After the paper convolute has been cut off it is given a few more turns by the renewed engagement of the toothed gearing following the recess in the cog-wheel 2, Fig. 13, in order to wind up the rest of the strip forming the mouthpiece. At this moment a bolt or pawl 20, Figs. 2 and 13, falls into a recess in a disk 21 of the hollow spindle 1 owing to the raised edge or cam-surface 22 on the wheel 2 releasing a lever 22, operating the pawl. The rolling np device at this position of the pawl, Fig. 1, remains at rest until the new end of the paper band is introduced. During this period of rest the jaws are first eased to allow the mouthpiece to be pushed off into the cigshell or tube.

arette-shell. For this purpose the cam-disk 6 moves the lever 7 into the position III, Fig. 1, which causes the ring 11 to be pushed beyond the shoulder 12. The rolling-up tongs are thereby eased or partly opened, the ring being somewhat wider than the closed tongs. The jaw 5 is eased a little, Fig. 9, the presser 13, which otherwise would prevent the easing of the convolute, being lifted by the edge of the forwardly-moving ring 11 and kept in that position until the mouthpiece has been shifted from the rolling-up tongs into the cigarette Before the mouthpiece has completely entered the cigaretle'shell it will have passed out of reach of the presser and may therefore expand inside the shell, so as to become securely held therein. The apparatus represented in Figs. 1, 2, and 9, serving to hold the cigarette tubes or shells filled with tobacco up to the space reserved for the mou thpiece, form no part of this invention, and therefore require no description, any convenient form of holder being applicable. The shell being now removed, the lever 7 returns to its initial position I, the ring 11 passes back over the shoulder 12, and the jaws of the rollingup device are again open to receive the neXt strip of paper to be rolled up. The .point of the strip,which after cutting off the mouthpiece only reaches to the knife,is made to move a little forward to bring the point within reach of the jaws of the rolling-up tongs, as seen in Fig. 6. Thisis done by the forked lever 23 and spur-wheel 23, Fig. 12, acting on the carrier a to move the strip 1) forward to the required extent. During the forward movement of the carrier a the strip is held fast on the little ledge 24: by the clamp 25,actuated bya spring, Fig. On reaching the limit of the forward movement the clamp 25 is released by its projection 26 striking against a fixedprojection 27 to prevent it from being wedged during the first movement. The carrier being drawn back after its forward movement by the spring 28, the clamp will act as a brake when the end of the paper band is being rolled up to form the mouthpiece. The triangular piece of paper remaining after the mouthpiece is cut off is waste paper.

The above-described apparatus may be used either independently by itself or conjointly as part of a machine for producing cigarettes provided with mouthpieces.
